It's very interesting to see all the various sear configurations that have been involved with the Ruger Mark IV in the short year they've been out. Volquartsen has three, my last count. I do not, as yet, have a "Majestic Arms" Mark IV sear, but it's a plan I have, to get one. But, the post recall sear sure is a "fugly" little devil.
As it stands right now, some combinations of sear/hammer/disco work very well, and then again........some combinations will have me reaching for the Crown Royal.
Hammers and hammer bushing combinations to defeat the magazine disco parts is another interesting endeavor. I've found that the plastic magazine "ejector" gizzy, will in some cases, hinder the magazine from clicking positively up, and into place, and sometimes, will drop the magazine after firing only three rounds. On my personal Mark IV Competition Target I removed the black plastic ejector and the magazines click more positively into the latch yet still shoot out of the grip frame just fine when the release is pressed.
For all those owners who just LUV your Mark IV just as it is, I salute you. Just keep in mind that there are some of us who, "just gots to KNOW". I don't expect any patience or understanding on anybody's part, just furnishing some info to ponder for those of you who like to tinker and personalize your Mark IV pistol.
What's involved with "disco parts" ? Thanks, Garry
The disconnector ( trigger bar for some ) is another one of those internal parts that needs to be discovered as to how well they play with the sear. The factory disconnector ( disco ) works like it should with the factory sear. Question is:
"How well does the factory sear work with the Volquartsen disco"? Volquartsen recommends that their disco and sear for the Ruger Mark IV work best when married up together. OK, I want to find out if that's the case.
Then, we have the Majestic Arms Ruger Mark IV kits. Majestic Arms uses a unique disco that helps to eliminate quite a bit of the pre-travel in the trigger. The only issue some folks may find is that the Majestic Arms disco needs to be fit to the sear, according to the manufacturer. If, for some reason, the sear is changed, you may need to acquire a new disco and fit that one to the desired sear now installed. Or, you may get lucky and a different combo of disco and installed sear may work just fine.
It seems to me, at least when aftermarket parts are involved with the Ruger Mark IV, the Ruger engineers tried their best to thwart any changes to this pistols design. That may be a bit arrogant on their part because there are quite a few ingenious folks on this forum and several others who don't accept the statement:
"Well, that can't be done". There's a bunch of good folks at Volquartsen who've done pretty dang well by making parts that improve trigger pull weight, and function, on the Ruger Mark pistols, and several others who are working to get beyond these "bumps in the road" and improvement will indeed be realized.
And then, of course, there's always that small element of "dreamers" who choose to go way beyond anything practical. Here's a picture of a Ruger Mark II hammer that I was sent. The owner wanted to install "bearings" on each side of the hammer. I didn't even ask why, I just quoted him a price for the required "jig grinding" of the hardened hammer, and after payment, it was sent off to him. Never did hear how well it worked, or didn't.
Haven't even started on triggers and hammers yet.
